...To substitute the society of ideas for that of things is simply to live in the mind; it is to survey the world of existences in its truth and beau… - Benedictus de Spinoza

...Kant is Spinoza's only adversary in the realm of occidental culture. Constantin Bruner has aptly stated that everyone must be either a Spinozist or a Kantian. The modern intellectual world, however, is overwhelmingly Spinozistic. Kant created only a school of thought, but Spinoza gave birth to a new culture and religion. Kant was long forgotten in his own fatherland until he was revived by Hermann Cohen. Spinoza has always lived in the centers of modern culture. Although at first he was maligned, calumniated, and even damned, he came to be later blessed and admired. He was always a subject of discussion in religious, philosophical, and scientific circles, because he dangled before man's eye the picture of a world without contradictions or abuses. Kant has accomplished only a special task. He examined and described the mechanism of the human mind rather than the mechanism of the world. He can be compared to Aristotle, as Spinoza can be likened to Plato. Kant is the very embodiment of idealism, while Spinoza is the representative of extreme naturalism.

Of all the philosophers of the seventeenth century, perhaps none have more relevance today than Spinoza.

And therefore we can see just how constructive this Spinozian difference is, just how constructive this negativity really is! The organic interweaving of these two motifs is fundamental in the history of European philosophy. Spinoza is the first to mold this logical mechanism that bourgeois philosophy would constantly and continually try to abrogate during its subsequent development. In Kantianism, as in classical idealism, Spinoza continually remains the object of opposition and polemic: What is destroyed is precisely the intersection between the negation of the ideology and the construction of the world, the inherence of the limit, of the materiality, to the infinite.
